An iterative solution to nonlinear problems of time-periodic eddy currents is performed by directly using the time-harmonic content of the field quantities instead of time-domain techniques employing successive time steps. A linear sinusoidal steady-state field problem is solved to determine the magnetization harmonic…
To date there are potential chronology-based but not conclusive reasons to believe that at least some of the gadolinium complexes play a causative role in the pathophysiology of nephrogenic systemic fibrosis (NSF) or nephrogenic fibrosing dermopathy (NFD). Still, the exact pathogenesis and the risk for patients is unc…
Graphs are frequently used to describe the geometry and also the physicochemical composition of protein active sites. Here, the concept of graph alignment as a novel method for the structural analysis of protein binding pockets is presented. Using inexact graph-matching techniques, one is able to identify both conserv…
Gold (Au) nanowires (NW) have been synthesized by using mixtures of l -α-dipalmitoylphosphatidylcholine (DPPC) and various conventional surfactants (CS) of different polarities. The capping ability of the surfactant mixture has been quantitatively evaluated by using UV−vis, TEM, XPS, FTIR, and XRD studies. The synthes…
Abstract Electrochemical polarization and impedance spectroscopic (EIS) techniques were used to investigate the corrosion behavior of Ti‐5Al‐2Nb‐1Ta alloy in Hanks solution at different immersion periods (0 h, 120 h, 240 h and 360 h). The impedance spectra are fitted using a non‐linear least square (NLLS) fitting proc…
We investigate the magnetotransport properties of La0.7Ca0.3−xAgxMnO3 (0⩽x⩽0.3) polycrystalline films prepared by spray pyrolysis. The virgin La0.7Ca0.3MnO3 (LCMO) (x=0.0) film shows paramagnetic-ferromagnetic [insulator-metal (IM)] transition at TC∼260K (TIM∼245K). Ag doping induces appreciable enhancement in TC∕TIM…
The effect of the degree of deformation by high-pressure torsion (using five and ten revolutions of anvils) on the structure of niobium and its thermal stability under annealing has been studied using transmission electron microscopy. By deformation with five revolutions, nanocrystalline niobium with a grain size of a…
In present study, the feasibility of improving tribological performance of low carbon chromium steel by applying complex surface treatments which combines the method of Plasma electrolytic saturation (PES) is investigated. The different regimes of diffusion treatments on the surface affect the mechanical and tribologi…
Field programmable gate arrays (FPGAs) are important hardware platforms in various applications due to increasing design complexity and mask costs. However, as CMOS process technology continues to scale, standard copper interconnect becomes a major bottleneck for FPGA performance. This paper proposed utilizing bundles…
Silicone gel belongs to the group of room-temperature-vulcanizible silicone rubbers. It is a soft and conformable material with a certain tackiness. The work presented, describes the dielectric breakdown performance of silicone gel influenced by various stress conditions such as the presence of humidity or the influen…
An electron acceptor and a donor of perylene diimide dyes (4a, 4b) were synthesized in an effective way. And the π–π interactions between perylene diimide dyes were discussed in solution and in solid state. The existence of weak π–π interactions in 4a, 4b and their mixture was confirmed with UV/vis and fluorescence sp…
Propagation losses occur in medium voltage power cables as pulses propagate through them. Since cables have many components, these can make different contributions to the propagation losses. The relative contributions of the conductors, insulation and semi-conducting screens to the propagation characteristics of the c…
Abstract Fibre and filler flocculation, filler retention and drainage, induced by several polymeric retention aids, were compared in laboratory experiments on mixtures of kraft fibres and two calcium carbonate fillers. Some experiments were also performed on thermomechanical pulp and de‐inked pulp fibres. Flocculation…
Thread‐like nuclei for the crystallization of polymers which are formed at high deformation rates in a temperature range close to the equilibrium melting point appear to be practically stable at temperatures where spherulites are melting. However, the fact that the great majority of experiments on flow induced crystal…
A method is presented which determines the steady-state solution of nonlinear eddy current problems. The unknown potentials are represented by Fourier-series and the nonlinear behavior of the material is split into a linear and a nonlinear term using a fixed-point technique. This approach leads to decoupled linear equ…
Crumpled sheetlike carbons (SLCs) of a quasi-2-D graphite structure are continuously synthesized by thermal decomposition of methane using a dc plasma torch of hollow electrodes type operated in a reversed polarity mode. Field-emission scanning electron microscope images show that the products synthesized solely consi…
[64Cu]Cu(II)-ATSM (64Cu-ATSM) and [18F]-Fluoromisonidazole (18F-FMiso) tumor binding as assessed by positron emisson topography (PET) was used to determine the responsiveness of each probe to modulation in tumor oxygenation levels in the SCCVII tumor model. Animals bearing the SCCVII tumor were injected with 64Cu-ATSM…
This research is directed at the development of Electrostatic Actuated NAno Tensile testing devices (EANATs) for measuring mechanical properties of carbon nanowires, deposited by focused ion beam-assisted chemical vapor deposition (FIB-CVD) using phenanthrene gas. The EANATs were composed of the specimen part, actuato…
Injection molded short natural fiber composites (NFC) are studied in this article. Micromechanical models are employed to investigate effects of fiber length distribution, fiber orientation, and fiber/matrix adhesion on mechanical performance of NFCs. A parametric study showed that length/diameter ratio strongly affec…
A procedure is described for identifying a mathematical model of core losses in ferromagnetic steel based on a minimal amount of experimental data. The new model has a hysteresis loss multiplicative coefficient variable only with frequency, a hysteresis loss power coefficient variable both with frequency and induction…
